I don't know if this is the reason, but if it is, then you might
want to look at


It could also be that you're running a newer version of PHP that
has some low limits for PCRE matching (which PmWiki uses quite
heavily) that causes problem with long pages.  If so, you might
try setting in local/config.php:

    ini_set('pcre.backtrack_limit', 1000000);
    ini_set('pcre.recursion_limit', 1000000);

Future versions of PmWiki will likely set this as the default.
